Actor Guy Pearce has been added to the cast of Prometheus, according to an insider on the set. Here's an email excerpt from this insider, who is currently at Pinewood Studios in London where the movie is now shooting.

"Evening Nick, my mate is working on Prometheus as OMITTED and met Guy Pearce on set today. She's previously worked on OMITTED, OMITTED and OMITTED and I've no reason to believe she's lying. I've not read anywhere about Guy being cast so thought it might interest you."

It isn't clear what character Guy Pearce will play in Prometheus. Little is known about the story of Prometheus, although it is said to be in the same vein of the 1979 classic Alien.

Ridley Scott is directing Prometheus from a screenplay by Damon Lindelof, Ronald Shusett, and Jon Spaihts.
